We've seen quite a few programming projects lately, from CPUs built in the world of Minecraft to a full-blown Game Boy emulator in JavaScript. And now? Wiremod forum member Techni has taken the CHIP-8 virtual machine and got it up 'n running in the Garry's Mod sandbox for the Source game engine. Sure, CHIP-8 has been around since the 70s, and since it's small and easy to program it has a following that persists to this day -- but that said, we never expected to see it running Space Invaders from inside a game of Half-Life 2, in all its 8-bit glory. That's what we call progress! Or at least a satisfying hack. See it in action for yourself after the break.
